Breh, Kanye's superstardom didn't help Jay Z as Kanye's own star was fading during that period largely due to him singing instead of rapping and the whole Taylor Swift debacle.
Breh, 20/20 Experience was JT's third solo album, not his sophomore effort. Jay Z was featured on the lead single, which was the first single Justin had released in years. This wasn't the other way around.
Yes, he toured with him? Both JT albums, Jay Z's MCHG, Beyonce's self titled album, and some of a Nas album were recorded in the same Jungle studio during the same period in 2012-2013. There are pictures confirming this.
Jay Z discovered Rihanna and signed her. He was featured on the song that catapulted her career ("Umbrella").
Beyonce launched her solo career with Jay Z collaborations.
Know what you are talking about before you post. If you don't know, ask or do the research.
First off everybody knows back in 2009 Jay enlisted Rihanna and Kanye both who were bigger than him at that time on run this town. Let’s not forget that Jockin Jayz single flopped. Kanye was still a big star after releasing MBDTF. His buzz after releasing that album helped launched WTT.
My fault third album from JT. Still a 7 year break but was anticipated nevertheless. Jayz on the feature didn’t help the single it was more of coattail piggyback. It wasn’t frontin. Same thing can be said for Umbrella with Rihanna who was already a star at that time. Jay had that weak verse added to that song. On radio sometimes they wouldn’t even play Jayz verse.
BEYONCÉ was a bigger star than Jay. That no debatable.
